It came from the states, and is fitted with scrambler mudguards and knobbly tyres. It says Sei Giorni Special 124 on the side panels and looks like it's never been taken apart. It has a solid colour red tank.

I can confirm that the frame number is indeed of a Gilera 124 Sei Giorni Speciale.
The engine number is from a later 124 export model for the USA market.
The fuel tank should be white with black side panels and pin stripe.
Check out this cool ad, is this the same bike that you have got?
